Need a cost-effective packaging option that provides protection and presentation to your products? That is what our mailer cardboard inserts do. They make shipping an experience to remember. We increase your products’ safety with a custom fitment to keep them stable and secure. We craft these inserts with Kraft and corrugated materials. That’s why they are both durable and lightweight. The right inserts will act like a cushion and provide the utmost support for your products. Therefore, they minimize risks of any damage to the shipment, hence decreasing returns. Our cardboard packaging inserts are stylish and durable. Your logo in a printed tray promotes your branding goals and enhances perceived value. A divider provides clear compartments for multiple products. An inlay is used to protect the weak structure, such as electronics or glass jars. These cardboard mailing inserts can be used with eCommerce, subscription, and direct-to-consumer brands.
You handle the look. Select natural Kraft, full-color printing, or foam inlays as additional security. We test to ensure a fit and functionality. In addition to protection, our inserts improve the unboxing experience. They also decrease fillers and wastes. That will make packaging more sustainable.
